You will see two nuts with springs under them. Pressure switches with an adjustable differential have a smaller second set-screw. An air compressor will start (Kick On) when the pressure (PSI) in the air tank drops to a pre-set PSI (example 90 PSI). Turn the screw clockwise to increase the differential or counterclockwise to decrease the differential pressure. Screw the pressure screw back into its place slowly. When deciding what the best pressure is for you and your compressor, always remember to set the pressure as low as possible for your application. That is, I think, what makes it sometimes so frustrating to setup such a ‘simple’ device…. This will burn the compressor motor, will cause extra wear on the compressor components and will damage the pressure switch. The pressure switch is also what signals the compressor to kick on when the pressure drops too low (cut-in pressure). It reveals the parts of the circuit as simplified forms, as well as the power and also signal connections between the tools. Turn the screw clockwise to increase the differential or counterclockwise to decrease the differential pressure. In other words, is it the pressure switch setting, or is it the outgoing air regulator setting? Picking the right air compressor pressure switch starts with learning the pressure requirements of your air compressor. It’s the compressor pressure switch that turns the air compressor on and off depending on the switch settings. If it’s adjusting the downstream pressure to your tool, that’s done with the air regulator. Read on and learn more about air compressor pressure switch.

Be sure not to touch the electrical terminals, turning the circuit breaker off is recommended. Let the air compressor run until it shuts off. The compressor will run until the cut-out pressure is reached. By adjusting the cut in and cut out pressure, a pressure switch allows the air compressor to do so. The air compressor pressure switch measures the pressure inside your air tank and shuts off your compressor when it reaches the air pressure you need. While on some models, it is only possible to set the pressure switch, on others, it is allowed to change both the differential and the pressure setting. We have a separate post about setting the pressure switch. I want to set the performance pressure to 145psi. Write down the pressure. [12v vs 18v Drill], Gun Grease vs Oil – All About Gun Grease and Lubricating Oil. I have made a basic overview of different models and types of pressure switches. Many air compressors come with a whole range of different features, but the majority of them will come with a pressure regulator. 8 Conclusion. Pressure differential is 1 bar. Make note of the pressure when the switch pops up and adjust the bolt as needed to get the desired pressure. Note the pressure at which the machine stopped last time you let it run. You have now successfully set the pressure switch. Some pressure switches have a secondary spring (usually smaller than the primary spring) that will adjust the cut-out pressure without affecting the cut-in setting. Set the cut-out pressure second. The air compressor will start immediately. Starting from an empty tank. Next, turn the air compressor on, check if it is running in the cut-in pressure, and stop in the cut-out pressure or not. How do you adjust cut in and cut out pressure? Turn clockwise to increase (if you want a higher maximum pressure) or count-clockwise to decrease (if you want a lower maximum pressure. An air compressor will start (Kick On) when the pressure (PSI) in the air tank drops to a pre-set PSI (example 90 PSI). Proper adjustment of an air compressor pressure regulator is important for the smooth functioning of your air compressor and air tools. But if you only need 5 or 6 bar, it’s better to lower the pressure. In other words, is it the pressure switch setting, or is it the outgoing air regulator setting?

The unloader valve is swivel based and can be adjusted to fit the unloader tube if … Yes, you can adjust the cut-in and cut-out pressure level yourself, but I think that with your switch you will be trying to adjust it in vain. Remember, for every complete cycle of the screw, the pressure will increase 2 ½ PSI. Identify your pressure switch. Compressed air quality: how clean do you want your compressed air? Turn clockwise to increase the cut-in pressure. Look at the pressure gauge for the tank itself. Now adjust the set-screw (the big one), clock-wise (increase cut-in pressure) until the compressor starts. Thinking about it, this makes sense, as this is the most important thing for your machine to operate properly (they will operate properly on a higher pressure, but not on a lower pressure). If you adjust your cut-on pressure you will also need to adjust the pressure tank air charge. Note the pressure at which it starts (the cut-in pressure). Both for small (piston) compressors and for large industrial rotary screw compressors, the pressure setting is the most basic and most important setting of the compressor. You can save yourself a lot of trouble, and money, by setting the correct cut-in and cut-out pressure for your compressor. Your email address will not be published. We call the difference between cut-in and cut-out pressure the pressure band or the pressure differential. Just set the cut-in and cut-out pressures, right. 6 Maintenance for a pressure regulator. The pressure tank should be set at 2 PSI less than the cut-on pressure. It also controls the compressor cut out pressure level too. You can call this difference the pressure band, as I stated earlier. The procedure is somewhat the same as for the cut-in pressure. These two pressures have a measurable difference, which is known as the pressure band. Observe the compressor's pressure gauge while it is running and take note of the pressure reading when it stops running. You will control it by moving the switch clockwise and anticlockwise.

On large compressors, it’s done on the central compressor controller, but the idea is the same. So if you don’t find any problems with the safety valve, then check the pressure switch. The pressure switch turns the compressor on when it hits the lower pressure setpoint and turns the compressor off when the upper setpoint is reached. The smaller screw, the differential setting, then sets the maximum pressure, the cut-out pressure, relative to the cut-in pressure. Presssure setting of the air compressor is the most important and basic thing to keep in mind for both small and large compressors. A wiring diagram is a simplified traditional pictorial depiction of an electric circuit. How the Air Compressor Pressure Switch Works. Recently replaced pressure tank filter to resolve blotter test issues (oil in the blast air) and it fixed the problem. line going to the unloader valve (Photo 1).
